DETAILED DESCRIPTION
Warmth and Interior Comfort
You'll appreciate the Hot Stuff 3.0 and Silk Stuff 2.0 linings. The Hot Stuff 3.0, with its large-loop structure, excels at retaining heat. The Silk Stuff 2.0 feels incredibly soft against your skin and boosts flexibility. Together, these linings provide effective insulation for temperate waters without ever restricting your movement.
Flexibility and freedom of movement
The Seek Core 4/3 Overknee LS is crafted from Natural Rubber. This maximizes its elasticity. Its seamless shoulder design and minimal paneling reduce any snag points. You can move freely during maneuvers and when getting back on your board.
Front Closure and Easy Adjustments
The ergonomic front zip, combined with the One Hand Zipper system, FZ Cordlock, and a replaceable cord, allows for effortless one-handed wetsuit adjustment. This feature is especially handy on the spot when the wind picks up and the cold sets in.
Durability and Water Protection
GBS seams, Maki_Tape 2.0 reinforcements, and additional Seam Reinforcements significantly boost durability. They minimize water infiltration. The Water Defender Leg and reinforced drains prevent water from flushing up through the legs. You stay warmer for longer.
Practical details
This wetsuit includes a key pocket with a loop, separate leg straps, and reinforced drainage holes at the chest and legs. These thoughtful details make daily use simpler and more secure.
Material Commitment
This wetsuit replaces traditional neoprene with Natural Rubber, derived from oyster shell powder, soybean oil, and eco-carbon black. The linings are made from recycled fibers. This significantly reduces the environmental footprint without compromising performance.
